Lubuntu 23.10 (mantic minotaur) released

Lubuntu 23.10 (mantic minotaur) Released!

The Lubuntu team is proud to announce another successful release. Lubuntu 23.10 Mantic Minotaur, the 25th release of Lubuntu and the eleventh to feature LXQt as its default desktop environment.

Support lifespan

With Lubuntu 23.10 being an interim release, it will follow the standard non-LTS support period of nine months; this means that Lubuntu 23.10 will be supported until July 2024. Our development focus going forward will be on Lubuntu 24.04 LTS and future releases, so only critical bugfixes and security updates will be provided. If you choose to use Lubuntu 23.10, we STRONGLY recommend upgrading to 24.04 LTS soon after it is released, but before Lubuntu 23.10 hits end of life. If this is not suitable for you, but you still enjoy new features on a regular basis, we would recommend staying on Lubuntu 22.04 LTS with Lubuntu’s Backports enabled.


You can download Lubuntu 23.10 here. If you would like to upgrade your existing 23.04 installation, please visit our manual page describing the process. Common Ubuntu instructions can be found here.

Known Issues and Notable Changes

Firefox whilst release-upgrade is running

If during release-upgrade from Lubuntu 23.04 to Lubuntu 23.10, you have a firefox window open, the text may become unreadable. If you need to use firefox during the upgrade, just close and restart the app (when text is unreadable), as there are font changes occurring which cause this minor issue during upgrade.


A bug in LXQt results in duplicate menu entries for the Calamares installer, showing the following:

While either of these options work, we recommend using the desktop icon.

System Installer

We are once again utilizing Calamares 3.3 Alpha 2 in Lubuntu 23.10, as it has proven to be highly reliable since its initial use in Lubuntu 22.10.

During testing, we did note that if you attempt to create an encrypted installation without a passphrase, Lubuntu will be installed unencrypted. This is unlikely to be a problem for most users as disk encryption requires a passphrase for it to be effective. More information can be found here.

Fonts change

As noted in the Ubuntu 23.10 Release notes there is a new Ubuntu font being used. Some users have expressed displeasure with this change (including some Lubuntu 22.04 LTS users using backports), so if you’d like to return to the older Ubuntu font, you can install the fonts-ubuntu-classic package to continue using what Lubuntu 23.04 provided.


We have a new wallpaper (which is also used as at the login screen), created one of our Lubuntu Members; Walter Lapchynski, with a bit of assistance from Ubuntu Studio’s Erich Eickmeyer. Thanks to both Walter and Erich.

What is Lubuntu?

Lubuntu is an official Ubuntu flavor which uses the Lightweight Qt Desktop Environment (LXQt). The project’s goal is to provide a lightweight yet functional Linux distribution based on a rock-solid Ubuntu base. Lubuntu provides a simple but modern and powerful graphical user interface, and comes with a wide variety of applications so you can browse, email, chat, play, and be productive. You can find the following major applications and toolkits installed by default in this release:

You can find a variety of other applications installed which aim to enhance your experience while staying out of the way of your normal workflow. New features and bugfixes in core Ubuntu components can be found here.

Lubuntu Manual

The Lubuntu Team has been hard at work in polishing the Lubuntu Manual to make it easy for new and experienced users alike to use their system more productively. The manual can be found at We want to thank Lyn Perrine for all the hard work she has put into the Lubuntu Manual. Thank you!

Versions of the Lubuntu Manual:

While the documentation for previous releases will be kept in the Git repository, they will not be published anywhere.

We would also like to thank the following past members for their dedication to the project. Without you, Lubuntu would not be what it is today. Thank you!

Global Team

The Lubuntu Global Team has been created to foster communities in non-English languages and locales. An up-to-date list of our communities can be found on our Links page, but the existing groups include: Spanish, Portuguese, Russian, Italian, Chinese, German, Japanese, Arabic, and French. If you would like to start a language group, join our development channel and talk with the Global Team. At minimum, you should have a few interested drivers of the community, and at least one administrator that speaks English. We now have multiple languages available in the support section of our Discourse forum.

I’ve been meaning to check in and congratulate all those involved. From my observations, it’s a pretty solid release - especially for an interim release. We’ve got a great team involved.


I agree with KGIII, it’s a pretty solid release - especially for an interim release. We’ve got a great team involved :+1:


Looking forward to trying out this release.

Are there any reported issues upgrading from 23.04? I’ve gone through the manual numerous times to make sure I’m attempting to upgrade properly, but I always get “No new release found.” To be sure, my Software Sources > Show new distribution releases: Normal Releases

I’ve written an answer here that maybe useful - updates - Cant upgrade from ubuntu 23.04 to 23.10 - Ask Ubuntu (with another of UF on this thread)

The answer was originally written rather early in the process, but if you read the comments I’ve added over time, you’ll note I’ve more detail at various points between then and now. The fridge announcement I mentioned I’d not yet made at one point, has since been made.

In summary

To view status you can read - Mantic Minotaur (23.10) Release Status Tracking - Release - Ubuntu Community Hub

where the release is still marked as “In Progress

If you don’t want to wait; you can force the upgrade as mentioned in release announcements - ManticUpgrades - Community Help Wiki

(If you don’t recall it being in ours, it was found in the link where we referenced Ubuntu/Common release notes)

The upgrade from 23.04 to 23.10 isn’t yet seen, because of what’s in this metafile - which will be changed when the Ubuntu Release team decide all issues on the upgrade have been released.

The only I’m aware of is listed as the BLOCKER ON ENABLING UPGRADES listed in the status tracking document; though in my own QA of that process I did not experience it; a Lubuntu user has to have firefox running during the upgrade to experience it; with it only impacting their firefox session.

I’ve seen work by Simon (@tsimonq2) on issues that maybe related to upgrades, but I’ve not paid enough attention to that to provide more.

I’d not expect the upgrade to be seen by your system (ie. Ubuntu Release team amending the meta release file) until early next week; but if they don’t do it; you can be rest assured their are reasons for their decision (they open the upgrade cycle for all 23.04 users, not just Lubuntu 23.04 users, so issues may impact other flavors we’re not as aware of for example).

If you don’t want to wait, refer to the ManticUpgrades link I provided, with the commands we used in our QA found in our checklist -


@guiverc thank you for the detailed (and very interesting) explination. I was not aware of the post availbility release process. Super informative.

Thank you very much!
